abstract

Recycled paper is helpful to reduce trash discharge, save resource and cost. Tube is one of the most common structures of recycled paper in application. It is an excellent choice for packing. It’s also used in the construction of temporary structures for both exhibition spaces or for rapid-recovery shelters in emergency operations. As paper tubes are laminated by paperboards which are inherent anisotropy materials, the researches on mechanical property and fracture behavior became complicated. In the current study, paperboards used for paper tubes were tested on universal testing machine to investigate their basis mechanical properties. Then, paper tubes fabricated with different kinds of paperboard and number of ply were used to investigate lateral compressive properties by Instron universal testing machine. And, a camera was employed to record the fracture process of paper tube during compression process. The fracture mechanism of paper tubes were discussed and analyzed during compressed process based on the load-displacement curves and detailed observation. Additionally, ls-dyna software was used to conduct numerical simulation and analyze stress distribution of paper tube during lateral compression.
